Mates rates, whilst I can't comment on how easy, or not, it is to get stuff out of the AsA system- not a pilot myself & its bad enough the 20 pages we have to read through before shift.
If in any doubt about the activity check with the local area freq, most of us ATCers would prefer it to infringing the airspace & the complicated call we have to make to the range officer.
Or failing that at least listen on the Area freq, me & most of my colleagues will blind broadcast a safety alert to aircraft seen to be heading towards active areas
